Description

Technical Field

[0001] The utility model relates to the technical field of soil moisture retention, in particular to a moisture retention structure for safe production of low-cadmium-polluted farmland soil. Background Art

[0002] With the accelerated development of global industrialization and urbanization, heavy metal pollution, especially cadmium pollution, has become one of the important factors restricting the sustainable development of agriculture. Cadmium is a highly toxic heavy metal element. Through industrial emissions, mineral mining activities, and the irrational use of fertilizers and pesticides, it easily accumulates in the soil, thereby affecting the growth of crops, reducing the quality of agricultural products, and posing a potential threat to human health through the food chain. Traditional methods for treating cadmium-contaminated soil mainly include physical remediation (such as the soil-injection method), chemical remediation (such as the leaching method), and biological remediation (such as phytoremediation). Although these methods have achieved certain results, they are often costly, have long cycles, and may disrupt the ecological balance of the soil, affecting the sustainable production capacity of farmland. In particular, how to maintain soil moisture during the remediation process to ensure normal crop growth has become a technical bottleneck that needs to be solved urgently.

[0003] Soil moisture retention is key to maintaining crop growth and enhancing soil ecological services. In cadmium-contaminated farmland, a suitable moisture retention structure can reduce water evaporation, increase rainwater infiltration, improve the soil microenvironment, and promote root development. It also helps to fix and transform cadmium ions in the soil, reducing the risk of their migration to crops. Therefore, a moisture retention structure for safe production in low-cadmium-contaminated farmland is needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a moisture retaining structure for safe production of low-cadmium-polluted farmland soil.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A moisturizing structure for safe production of low-cadmium-polluted farmland soil comprises a moisturizing main water pipe and several moisturizing subsidiary water pipes. The top of the moisturizing main water pipe is connected to a water inlet pipe, a control valve is fixedly installed on the water inlet pipe, the moisturizing main water pipe and the several moisturizing subsidiary water pipes are connected via a connecting hose, a plurality of water outlet holes are evenly and equidistantly provided on the outer side wall of the moisturizing subsidiary water pipe, and an anti-clogging component is provided outside the moisturizing subsidiary water pipe.

[0007] Preferably, the outer side wall of the moisturizing main water pipe is connected to a plurality of water outlet pipes, and the moisturizing auxiliary water pipe is connected to a plurality of water inlet pipes;

[0008] The water outlet pipe corresponds to the water inlet pipe in a one-to-one manner, one end of the connecting hose is connected to the water outlet pipe, and the other end of the connecting hose is connected to the water inlet pipe;

[0009] It is used to connect the moisturizing auxiliary water pipe with the moisturizing main water pipe. After the moisturizing main water pipe and the moisturizing auxiliary water pipe are placed in appropriate positions, the water outlet pipe and the water inlet pipe are connected through a connecting hose of appropriate length to ensure the connectivity between the moisturizing auxiliary water pipe and the moisturizing main water pipe.

[0010] Preferably, the anti-clogging component includes a filter water pipe sleeved outside the moisturizing auxiliary water pipe, the outer wall of the moisturizing auxiliary water pipe is covered with a first geomembrane, and the inner wall of the filter water pipe is adhered with a second geomembrane;

[0011] A water-absorbing sponge is filled between the first geomembrane and the second geomembrane, and a plurality of through holes are evenly and equidistantly opened on the outer wall of the filter water pipe;

[0012] It is used to prevent soil from clogging the moisturizing auxiliary water pipe. After the water in the moisturizing main water pipe enters the moisturizing auxiliary water pipe through the water inlet pipe, the water flows into the first geomembrane, the absorbent sponge and the second geomembrane in turn through the outlet holes, and finally is discharged from the through hole on the filter water pipe, thereby realizing the slow discharge of water.

[0013] Preferably, the water outlet pipe passes through the moisturizing auxiliary water pipe, the first geomembrane, the water-absorbing sponge, the second geomembrane and the filtering water pipe in sequence from the inside to the outside.

[0014] The utility model has the following beneficial effects:

[0015] 1. By setting up anti-clogging components, the water in the moisturizing main water pipe enters the moisturizing auxiliary water pipe through the water inlet pipe, and then penetrates into the first geomembrane, the absorbent sponge and the second geomembrane in turn through the outlet holes, and finally is discharged from the through hole on the filter water pipe, thereby realizing the slow discharge of water.

[0016] 2. By setting up a connecting hose, after the moisturizing main water pipe and the moisturizing auxiliary water pipe are placed in the appropriate position, the water outlet pipe and the water inlet pipe are connected through a connecting hose of appropriate length to ensure the connectivity between the moisturizing auxiliary water pipe and the moisturizing main water pipe.
